AERIAL BOMB.

To all whom it may concern: I

Be it known that I, BOYD A. SIGLER, a citizen of the United States,residing at Sioux Falls, in the county of Minnehaha and State of SouthDakota, have-invented certain new and useful Improvements in AerialBombs, of which the following is a specification.

My invention relates to improvements in aerial bombs.

An important object of the invention is to 'provide a bomb of the abovementioned character having means whereby a plurality of relatively smallprojectiles are first thrown from the body of the bomb, upon the samestriking the ground or target, and sub-- sequent towhich the body of thebomb is exploded, and thrown in divers directions.

A further object of theinvention .is. to provide a. bomb of the abovementioned character, having the projectile receiving openings arrangedin the wall thereof, in

such a way that the wall is rendered breakable into sections, which areprojected in divers directions.

A further object of the invention is to provide a bomb of the abovementioned character which is automatic in operation. Other objects andadvantages of the invention will be apparent during the course of thefollowing description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame,

- tinuation of theshell 10.

' The shell 10 is provided with radially extending openings 14, whichpass through the inner and outer sides of the wall thereof. The openings14 are arranged in longitudinal and horizontal circumferential groups,providing relativelylarge portions or squares 14 which are readilybreakable from each other, by virtue of these openings, as will be morefully explained. These openings are adapted for thereception ofrelatively small projectiles or bullets 15. Instead of employing asingle bullet 15, I may employ a wrapper 16, filled with shot or smallprojectiles 17, as shown.

The shell 15 is filled with a propelling charge 18, and this charge,upon exploding,

forces the projectiles 15 through and from the openings 14.

The nose 13 is provided with an interior recess, filled by a plug 19.This plug has a chamber 20, and passages 21, formed therein. Thepassages 21 lead to the projecting charge 18, as shown.

Arranged centrally and longitudinally within the shell 10 is anexploding member 22, filled with an exploding charge 23. The member 22is inserted within a thin metallic casing 24, held in place bystationary lugs 25, secured to the shell 10. The member 22 is capable ofmoving forwardly longitudinally within the casing 25, and this movementis normally opposed and prevented by a compressible coil spring 26. Acombined cap and fuse 27 is secured to the plug 19 and.

leads to the chamber 20, while a longer combined cap and fuse 28 issecured to the lower end of the member 22 and leads to the interiorthereof.

When the projectile is dropped from a flying machine or the like, thesame descends by gravity and upon contacting with the ground or target,the member 22 moves forwardly with relation to the shell 10. Thismovement brings the combined cap and fuse $28 into contact with thecombined cap and fuse 26, whereby they are both ignited. The

sequent to this operation, the exploding.

charge 23 is ignited, and the entire bomb including the shell 25, isblown to pieces. The openings 14 by'being arranged inthe precise manner,as illustrated in Fig. 6, form relatively. large portions or squares14', which are readily breakable from each other, and

these portions or squares are projected in divers directions. a

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvariouschanges in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of my invention or thescope of the subjoined claims.

Having thus described my invention, I claim i 1 1. An aerial bomb of thecharacter described, comprising an outer shell having a plurality oftransverse projectile openings,

projectiles for insertion in the openings, a

cap secured to the forward end of the outer .shell and having aninterior recess, a plug arranged within the interior recess and having amain inner chamber and ports extending outwardly therefrom and leadinginto the interior of the outer shell, an inner tube extendinglongitudinally of the outer shell, a firing charge arranged Within thespace between the outer shell and inner tube and leading-to the ports, acasing mounted rei ciprocate within the inner tube, an exploding chargearranged within the casing, a combined cap and'fuse anchored withintheinwardly beyond the casing, said second named combined cap and; fusebeing substantially longer than the first named combined cap and fuseandadapted to contact with the first named combined cap and fuse, and

yielding means to; oppose the forward movement of the casing.

2., A device :of the character described,

comprising an outer casing having a plurality of transverse openings,projectlles for insertion within the openings, an inner tube extendinglongitudinally within the outer casing, an exploding charge arrangedwithin the outer casing exteriorly of the inner tube, an inner casingarranged within the longitudinal tube and adapted to moveforwardly-therein, means to'oppose the forward movement of the innercasing, an exploding charge within the inner casing, and'means operatedby the forward movement of the inner casing to, fire the first namedexploding charge and subsequently fire the second named explodingcharge.

In testimony whereofI aflix my signature.

BOYD A. SIGLER.
